This recipe for kahlua coffee soda makes a refreshing caffeinated beverage that is also spiked for unwinding, or simply some summer time fun. Created by Cindy at the food blog Hungry Girl Por Vida, the energizing cocktail is like an adult version of its inspiration -- a classic egg cream drink. The four ingredient refresher is ideal for cooling down this season, either as a naughty mid-day pick-me-up, or an energy-boosting option at night.

You can try the homemade kahlua coffee soda by mixing a shot of espresso, kahlua coffee-flavored liqueur, black walnut or aromatic bitters and soda water. It is also a good idea to add ice and half and half, giving the fizzy and creamy drink an esthetically pleasing swirl.
